Page notes last updated 2005-10-22; no personal byline visible. First-person Eremowhat seedling account is explicitly distinct from Coachella Eremolemon. The page discusses Swingle's Meyer-lemon parent hypothesis and later-editor doubts, and says Oregon Exotics Razzlequat is almost certainly Coachella Eremolemon with no kumquat ancestry; this is a secondary identification, not accession proof.

Blog post discusses uncertainty around Razzlequat/Coachella Eremolemon naming and parentage; it proposes a grapefruit cross, conflicting with UCR's reported Meyer lemon parentage. Reports a Savannah, Georgia test plant surviving 13°F/-11°C with poor acclimation, but gives no accession, rootstock, exposure duration or damage details.

Summarizes an HLB inarching study. It calls Eremolemon a naturally occurring Australian desert lime × Meyer lemon hybrid and reports an HLB response score of 2/8 and nucellar progeny; the Eremolemon accession is not identified. In the described trial, Eremolemon inarches did not impart resistance/tolerance to Valencia scions. Do not infer this is CRC 2439 or treat it as a successful grafted-tree resistance result.

Summary from transcript: English auto-generated captions, 0:00–6:49 of 6:58. At 0:37–0:49 the presenter calls the shown tree Razzlequat / Coachella Eremolemon. They say it is easy to grow but hard to fruit, and report the pictured tree has set fruit after decent care this year (1:11–1:27). At 1:58–3:00 they describe a long-held grafted plant in a likely 3–5-gallon pot and many thorns, while expressing uncertainty about parentage beyond a desert-lime component. At 3:40–5:05 they describe one fallen fruit sample; this report does not establish an accession or cold-test identity.

Summary from transcript: English auto-generated captions, 0:00–11:32 of 11:32. The presenter identifies and cuts a Razzlequat / Coachella Eremolemon sample at 1:32–3:15. The largest fruit on the tree is reported as 34 mm after an initial spoken unit slip; more typical fruit is described as about 25 mm. The presenter reports one seed in the cut fruit. At 3:19–3:38 the speaker reports an 8 Brix refractometer reading; the instrument display was not visually verified. At 3:41–3:51 they describe a lime-like taste with a little off-flavor that was not distracting; at 4:09–4:26 they say the rind is not something they would eat like a kumquat. No sweetness, sourness, or bitterness intensity is assigned; these are not independent taste ratings from the scorecard or another video sample.
